Similar ones are available here in Israel. I assume since we use the same
electrical system as the UK, they are available there too.

There are also cheap junk, but I avoid them.

BTW, I've been using them since the late 1990's and CFLs keep getting cheaper,
more efficient and on the whole better. They are not perfect, and we still use
incandescent bulbs in some places, but 99% of the light in my home is from
either CFLs or the old fashioned long ones.
